The German research institute has proposed a technique based on the surface structure of the wings of the morpho butterfly to produce colored BIPV panels for facades and rooftops. The process is claimed to make it possible to color the modules with an optical effect and not with color pigments, which reduce their efficiency.

The Indian solar manufacturer has announced the release of its DESERV Galactic Ultra line, which includes the world’s first mono-facial modules to cross peak output of 500 W, using G1-sized (158.75 mm) cells.

Recovering silicon of the quality required for reuse in panels is at the heart of mitigating device carbon footprints. R&D efforts should be ramped up now, says an international research group, so the technology is in place when huge volumes of modules begin to need replacing.

The module is available in five versions with power output ranging from 310 W to 330 W and efficiencies between 20.22 and 21.53%. The Chinese manufacturer claims the BIPV panel has an oustanding flexibility with minimum curve radius of 25 cm.

The system can metallize the front and back sides of silicon solar cells with unprecedented precision and speed, Fraunhofer ISE said. The technology is also suitable for components such as printed circuit boards or chip cards.

Researchers in China have sought to understand how soiling exacerbated by anti-reflective coatings might inhibit solar panel output. In terms of effectiveness against soiling, the scientists found hollow-silica-nanoparticle coatings did better than solid silica alternatives.

Backsheet manufacturer Tomark-Worthen LLC has developed a new polyamide backsheet under the U.S. Department of Energy’s Sunshot initiative. The product is based on a novel polyamide-ionomer alloy created by U.S. chemicals producer Dow. The alloy, as well as the other materials in the backsheet, are stabilized with a UV/anti-oxidant package that slows down the damaging effects of ultraviolet radiation. The manufacturer claims that the backsheet is 25-30% more affordable than high-efficiency fluoropolymer products.

Chinese manufacturer Amerisolar and Brazilian energy company Nova Renováveis are planning to set up a 200 MW solar module manufacturing facility in Belo Horizonte, in the Minas Gerais state.

Trina Solar has been producing its 500 W modules in series for a month now and plans to increase their output to more than 600 W in the future.

Solaria says that it will start selling its new all-black panel for residential PV applications in the U.S. market within the current quarter. The monocrystalline module is equipped with a microinverter from Enphase and has an efficiency rating of 20.2%.
